Yes, you can separate the rotor assembly from the snout and case, and just keep that. It will also save weight in shipping, as thats the heaviest part of the blower.
Do you, or somebody you know own a torque wrench? You will want to use one when you put everything back together, and of course reinstall it onto the engine. Just a heads up.
What other brackets, and misc parts do you have in mind? Give a list, or take a picture of it all.
Know what looks bad ass on white IMO, chrome. The bolts to the blower and other hard wear near or on the other things you are thinking about having done in white, getting the hard wear chrome plated would look so hella bad ass.
Just throwing that out there in case your interested.
